[0003] Traditional clamps often struggle with workpieces of enormous size, resulting in sawing vibrations and rough cut surfaces due to insufficient clamping force. Furthermore, the random posture and center of gravity of scrap steel on the conveyor chain prevent continuous and uniform feeding, causing the saw blade to frequently spin idly or jam, wasting resources, accelerating wear, and affecting processing efficiency.

[0042] Further, the upper surface of the platform 18 and the lower surface of the pressing blocks 41 are both provided with rubber non-slip pads.

[0043] Further, the second driving motor 46 drives the lead screw to rotate, drives the movable frame 47 to move, and then the first clamping blocks 44 and the second clamping blocks 43 are clamped, so that the pressing blocks 41 are fixed.

[0044] The movable box 3 is provided with an extension plate 15 above the frame 8, and a first camera is arranged on the extension plate 15.

[0045] The inside of the conveying table 4 is provided with a track 17, conveying frames 34 are movably arranged on both sides of the track 17, a second mounting block 26 is mounted on the output end of the first cylinder 11, a first toothed plate 27 is arranged on one side of the second mounting block 26, first and second rotating shafts 25 and 30 are installed on both sides of the inside of the base 1 through shaft couplings, first and second driven gears 28 and 29 which are engaged with each other are sleeved on the first and second rotating shafts 25 and 30, and the first driven gear 28 is engaged with the first toothed plate 27.

[0046] Further, the conveying frames 34 are placed with top blocks 48, and scrap steel is placed between the top blocks 48.

[0047] The second rotating shaft 30 extends below the conveying frame 34 and is welded with a roller, the roller is sleeved with a rack 31 in tension, and a plurality of third and fourth rotating rods are installed on both sides of the conveying table 4 through shaft couplings, first movable blocks 33 are sleeved on the third and fourth rotating rods, a transmission gear 32 is welded on the lower first movable block 33 and engaged with the rack 31, a second movable block 35 is hinged between the two first movable blocks 33, a third rotating shaft 37 is welded on one side of the second movable block 35 and sleeved between the conveying frame 34 and the third rotating shaft 37.

[0049] The conveying frame 34 drives the top block 48 to top and abut, and the scrap steel is transmitted in a spaced cycle to ensure that the size of the cut scrap steel is uniform, improve the automation efficiency and the uniformity of subsequent processing, and through the cooperation of the ratchet wheel 36 and the pawl 38, when the first cylinder 11 drives the first toothed plate 27 to rise, the pawl 38 cannot be clamped on the ratchet wheel 36, thereby driving the second rotating shaft 30 to rotate, further driving the rack 31 to rotate, and realizing the driving of the first movable block 33. When the first cylinder 11 drives the first toothed plate 27 to descend, the first driven gear 28 rotates counterclockwise, and the second driven gear 29 rotates clockwise, trying to drive the second rotating shaft 30 to rotate clockwise. At this time, when the ratchet wheel 36 tries to rotate clockwise with the second rotating shaft 30, the tip of the pawl 38 is clamped into the vertical surface of the ratchet wheel tooth, preventing the clockwise rotation of the ratchet wheel 36 and the second rotating shaft 30, facilitating the resetting of the first cylinder 11. Although the first toothed plate 27 moves, the first driven gear 28 rotates counterclockwise, and the second driven gear 29 tries to rotate clockwise, the second rotating shaft 30 is locked by the pawl 38 and cannot rotate.

[0050] The third driving motor 19 is screw-mounted on the first mounting block 2, the output shaft of the third driving motor 19 extends into the first mounting block 2 and is sleeved with the first synchronous belt 21, the bottom inner side of the first mounting block 2 is installed with the rotating ring 22 through the shaft coupling, the first synchronous belt 21 is tensioned between the rotating ring 22, and the end of the rotating ring 22 is installed with the first rotating rod 50 through the shaft coupling. The first rotating rod 50 is sleeved with the rotating plate 39, and the rotating plate 39 is screw-fixed between the movable box 3.

[0051] The base 1 is provided with a groove 10, the first conveying belt 12 is installed above the groove 10, vertical plates 24 are screw-fixed on both sides of the groove 10, a first driving motor 7 is screw-installed on one side of the vertical plate 24, the first driving motor 7 is used to drive the first conveying belt 12, the first connecting strip 14 is hinged between the vertical plates 24, a plurality of nozzles are installed on the lower surface of the first connecting strip 14, a water tank 40 is fixedly arranged on one side of the base 1, a water pump is arranged in the water tank 40, a connecting pipe 13 is connected with the water pump in a pipeline manner, and the connecting pipe 13 extends into the first connecting strip 14 and is connected with the nozzles in a pipeline manner.

[0052] Working principle:

[0053] In use, the device is used by placing scrap steel on the track 17 of the conveying table 4, placing the two ends of the scrap steel on the top block 48, driving the movable plate 6 and the push plate 16 to push the scrap steel forward through the spring damper by the first electric telescopic machine 5, driving the first toothed plate 27 to rise by the first cylinder 11, rotating the first driven gear 28 clockwise, further driving the second rotating shaft 30 to rotate counterclockwise, further driving the rack 31 to rotate, driving the first movable block 33, driving the conveying frame 34 to make continuous progressive action, and feeding the scrap steel into the platform 18 through cooperation with the first electric telescopic machine 5.

[0054] When the scrap steel moves to the platform 18, the second connecting strip 45 is driven to move downward by the second cylinder 42, so that the frame 8 and the fixed box 9 connected by the second connecting strip 45 move downward, the fixed box 9 contacts the scrap steel through the pressing block 41 below the fixed box 9, the second drive motor 46 is started, the screw rod drives the movable frame 47 to move forward, so that the first clamping block 44 in the movable frame 47 clamps the second clamping block 43 arranged on the top of the pressing block 41, and the scrap steel is fixed.

[0055] The first synchronous belt 21 is driven by the third drive motor 19, further driving the rotating ring 22 to rotate, further driving the rotating plate 39 to drive the movable box 3 to rotate, realizing the position adjustment of the cutting strip 23, and starting the cutting process of the scrap steel.

[0056] After cutting, the second cylinder 42 is reset, the first cylinder 11 and the first electric telescopic machine 5 drive the scrap steel to feed equally, and the cutting operation is performed.

[0057] After the whole cutting is completed, the first electric telescopic machine 5 is reset, the first cylinder 11 drives the first toothed plate 27 to descend, drives the first driven gear 28 to rotate counterclockwise, drives the second driven gear 29 to rotate clockwise, and tries to drive the second rotating shaft 30 to rotate clockwise. At this time, the tip of the pawl 38 will be clamped into the vertical surface of the ratchet tooth when the ratchet 36 tries to rotate clockwise with the second rotating shaft 30, preventing the clockwise rotation of the ratchet 36 and the second rotating shaft 30. Although the first toothed plate 27 moves, the first driven gear 28 rotates counterclockwise, and the second driven gear 29 tries to rotate clockwise, because the second rotating shaft 30 is locked by the pawl 38 and cannot rotate, the rack 31 installed on the second rotating shaft 30 also remains stationary and does not rotate, the conveying frame 34 does not move, and the first cylinder 11 resets normally.

[0058] The scrap steel after cutting is conveyed by the first conveying belt 12 and sprayed with rust remover through the first connecting strip 14 on the top.

[0059] In this embodiment, because the shapes and thicknesses of the scrap steels are different, there are differences in fixing the scrap steels.

[0060] When cutting thin plate scrap steel with large area but easy to deform such as automobile shell, household appliance panel, etc., the scrap steel is erected on the top block 48, the bottom of the scrap steel is pushed by the push plate 16 driven by the first electric telescopic machine 5, when the scrap steel moves to the platform 18, the two fixed boxes 9 on the two sides are contacted with the scrap steel by the bottom pressing block 41 under the action force of the second cylinder 42, the pressing block 41 flattens the thin plate, which facilitates complete fixation on both sides of the cutting point, after the pressing block 41 is stable, the movable frame 47 is moved by the second driving motor 46 to make the first clamping block 44 and the second clamping block 43 clamped, the cutting bar 23 is vertically downward for cutting treatment at this time, and the above operation is repeated to obtain the scrap steel cut to equal length.

[0061] In the process of fixing the special-shaped part, the fixed box 9 is lowered by the second cylinder 42 to make the pressing block 41 abut against the special-shaped part, because the special-shaped part has different shapes and is irregular in shape, and the surface is uneven, after the pressing block 41 is contacted with the surface of the special-shaped part, the second cylinder 42 continuously applies a pulling force to drive the pressing block 41 to further contact with the surface of the special-shaped part, because the surface height of the special-shaped part is different, the height of each pressing block 41 is also different at this time, after the spring above the pressing block 41 is stable, the movable frame 47 is moved by the second driving motor 46 to make the first clamping block 44 and the second clamping block 43 clamped, at this time, the positions of different pressing blocks 41 are fluctuated, and the pressure of each pressing block 41 on the spring is different, which facilitates better limiting of the special-shaped part, and the cutting bar 23 is vertically downward for cutting.

[0062] In the above cutting operation process, the scrap steel is moved to one side of the platform 18 at the same speed by the first cylinder 11, so that the width of the scrap steel to be cut is also consistent, which facilitates subsequent collection and transportation to the next process for processing.

[0063] When cutting thick-walled pipes, it is difficult to fix the cylindrical pipes, so a V-shaped alloy clamping seat is added to the top block 48, the pipe is clamped in, the rack 31 is stepwise rotated by the first cylinder 11, and then moves to one side of the cutting bar 23, when moving to the platform 18, the fixed box 9 is lowered by the second cylinder 42, when the pressing block 41 abuts against the pipe wall, the movable frame 47 is moved by the second driving motor 46 to make the first clamping block 44 and the second clamping block 43 clamped, the pipe is limited, and the cutting bar 23 is vertically downward for cutting;

[0064] Further, if the length of the cutting bar 23 is less than the thickness of the pipe, the cutting is not complete at one time, at this time, after cutting to the depth of the cutting bar 23, the fourth driving motor 20 is turned off, the height of the cutting bar 23 is adjusted by the saw bed height adjusting mechanism (not shown in the figure) to make the cutting bar 23 sufficient to cut off the pipe, and the cutting is reset after completion.

[0065] Meanwhile, in the process of cutting the thick-walled pipe, the third driving motor 19 drives the first synchronous belt 21 to drive the rotating ring 22 to rotate, and the rotating ring 22 drives the first rotating rod 50 to rotate, and then drives the rotating plate 39 to drive the movable box 3 to rotate, and the cutting strip 23 is adjusted to 20°, and the pipe is cut at an angle, which further improves the service life of the cutting strip 23.

[0066] In example two, based on example one, the staff found that some thin plate type scrap steel such as frame and other special-shaped parts during use, and in the cutting process, only the pressing block 41 provided on the fixed box 9 is used to fix the scrap steel, and the thin plate type scrap steel cannot be completely in contact with the platform 18, and there is a possibility of shaking, which has a certain cutting risk.

[0067] Please refer to Figures 13-15 In example one, the extrusion table 55 is internally screwed into the conveying table 4, the extrusion table 55 is in contact with the track 17, and the width of the extrusion table 55 is consistent with the track 17.

[0068] Further, the movable groove 51 is provided on both sides of the conveying table 4, the sliding block 52 is slidably arranged in the movable groove 51, the L-shaped plate 53 is welded and arranged on the sliding block 52, the other end of the L-shaped plate 53 extends to the upper side of the conveying table 4 and is provided with the extrusion box 54, the inside of the extrusion box 54 is hollow, the limit plate 59 is welded on one side of the inside of the extrusion box 54, the connecting rod 62 is hinged to the top end of the limit plate 59, and the first rotating disc 60 is hinged through the connecting rod 62, the fifth rotating rod is arranged in the extrusion box 54 through a shaft coupling, the second rotating disc 61 is welded to the end of the second rotating rod, the vertical rod 57 is movably arranged between the first rotating disc 60 and the second rotating disc 61, the drop hammer 56 is welded to the outside of the extrusion box 54, the second electric telescopic machine 58 is arranged on the inside of the bottom of the extrusion box 54, and the end of the second electric telescopic machine 58 is welded to the connecting rod 62.

[0069] Further, the second tooth plate is arranged on both sides of the vertical rod 57, and the gear groove matched with the second tooth plate is arranged on the opposite surfaces of the first rotating disc 60 and the second rotating disc 61.

[0070] The second electric telescopic machine 58 drives the connecting rod 62 to deflect upward, and then drives the first rotating disc 60 to contact with the vertical rod 57, and then drives the vertical rod 57 to rise through the gear transmission, so that the drop hammer 56 moves upward, when it is necessary to extrude the thin plate type scrap steel on the extrusion table 55, the second electric telescopic machine 58 is retracted, so that the force on one side of the vertical rod 57 disappears, and the drop hammer 56 hits the scrap steel under the action of gravity, so that the scrap steel is extruded into a flat plate, which is convenient for subsequent fixing operation.

[0071] Further, when the scrap steel is subjected to the extrusion operation, the maximum thickness of the scrap steel before entering the extrusion table 55 is A, the maximum thickness after extrusion is B, the thickness of the scrap steel after cutting is C, and the length of the cutting strip 23 is D.

[0072] When B>D, the effective cutting depth D of the cutting strip 23 is less than the maximum thickness B of the scrap steel after extrusion, the cutting strip 23 cannot completely penetrate the scrap steel material in one cutting, resulting in incomplete cutting, at which time the height position of the cutting strip 23 needs to be adjusted, and secondary cutting is performed, so that the scrap steel in this section needs a long time in the cutting process.

[0073] Meanwhile, in the cutting process, the fourth driving motor 20 drives the cutting strip 23 to run at high speed, but the cutting resistance increases with the increase of the thickness, if B>D, the cutting strip 23 is easy to jam, overheat or accelerate wear, and even break, so that maintenance is needed after cutting is completed.

[0074] When B<D and the value of B is too small, the thickness B after extrusion is much smaller than the length D of the cutting strip 23, the cutting depth of the cutting strip 23 is excessive, at which time the scrap steel is not fixed firmly when the pressing block 41 is fixed, resulting in vibration or vibration in the cutting process, affecting the cutting precision and surface quality, at which time the edge of the scrap steel after cutting is deformed, resulting in a curved or wavy cutting surface, resulting in that the height C after cutting is not consistent with B.

[0075] Further, the second camera is installed on both sides of the conveying table 4, the second camera is arranged towards the extrusion table 55, the height B of the scrap steel after extrusion is observed through the second camera, if B is much smaller than D, the scrap steel is taken out, folded and placed on the track 17 after being pressed by the external hydraulic shearing machine, so as to facilitate subsequent cutting processing.

[0076] When C-B>1mm, the thickness C of the cutting scrap steel strip is greatly deviated from the thickness B after extrusion, at which time the video of the part on the extrusion table 55 subjected to the hammer 56 extrusion is analyzed through the camera, if the height difference at the hammer 56 is observed, it is proved that the part is not completely extruded, after cutting, the local area not pressed flat leads to C fluctuation;

[0077] Further, the pressing block 41 is not pressed uniformly, the scrap steel moves slightly during cutting, resulting in that the cutting surface is inclined, the value of C is deviated, the output power of the second cylinder 42 is increased to fix the subsequent scrap steel, so as to avoid shaking.

[0078] When A≈B, the camera does not monitor the change of the initial thickness of the scrap steel after the repeated operation of the drop hammer 56, and it is concluded that the scrap steel is too hard or is spring steel. At this time, the drop hammer 56 is raised by the second electric telescopic machine 58, a conical alloy pressure head is installed at the bottom of the drop hammer 56, and the scrap steel is penetrated by multiple rising and falling of the drop hammer 56, so that B reaches a cuttable value, and then the scrap steel is sent to the lower part of the cutting strip 23 for cutting treatment through the conveying frame 34.
